If you look on BB's website they are already planning on launching the FCFS balls later this year with the ability to pay for them online once you're on a ball. The reservation only ones are all orange, and it says the FCFS ones will be white with orange so they are recognizable. Their website explains everything. Cooper Island Beach Club is one of their partners as well as Anegada Reef, Leverick Bay, and Rhymers, so those BB's already in place in the prime spots most likely belong to those establishments.
